Well in the heat of an amazing threesome (two girls and one guy) the women contort their bodies into the bridge position and then the man places an Alaskan Pipeline (shitting into a condom and freezing it) into both women, connecting them. From there he karate chops the connecting feces bridge and empties the contents into their mouths.

Two drunks girls and one feces fetishing male are needed to create the shit bridge

Also known as shitbridging. for two grown ass niggas to hold both of each others hands and squat down to take a massive shit. This method is most commonly used in places that lack civilization And you don't want your bare ass to touch the nasty bug infested ground. You could also perform a reverse shitBridge together over a toilet if your both in a hurry to take care of business. You may acomplished the reverse shitbridge by locking elbows back to back.

You gotta shit bro? Me too dawg... help a nigga out and let's shitbridge.
